//! Regression tests for issue #797: chunking preset must not auto-inject embeddings.
|
|
//!
|
|
//! When a `ChunkingConfig` carries a `preset` but no explicit `embedding`, the
|
|
//! extraction pipeline must leave every `chunk.embedding` as `None`. Before
|
|
//! the fix, `resolve_preset()` silently injected an `EmbeddingConfig`, causing
|
|
//! `generate_embeddings_for_chunks()` to run and populate embeddings that the
|
|
//! caller never requested.
